hello. welcome to HCM.
you are having severe urinary tract infection
as indicated by urinanalysis. It would help better if you can get a test called as URINE CULTURE and ABST( antibiotic senstivity).This would reveal the organism and tell which is the antibiotic to which the causative organisms are sensitive. The results will take approximately 3 days.Till then you can start broad spectrum antibiotics and change over, if your organism is resistant to the one you are taking.
Whether, it is related to kidney
problem depends on your age and other results of urinanalysis.... protein, sugar and other results.
Hope this helps.
